Abstract
A dosing device for feeding infusion products including a dosing drum rotating about an axis and positioned between a continuous strip of filter material, movable along a feed direction, and a primary hopper for containing a primary infusion product; the dosing drum has a plurality of radial chambers for receiving a first dose of primary infusion product from the primary hopper and for releasing the first dose of primary infusion product above the strip of filter material; the device also includes an independent dosing unit of a secondary product including controlled release elements configured for depositing a second dose of secondary product to define a mixed dose of primary product and secondary product.

A dosing device for feeding infusion products, comprising:
- a dosing drum rotating about an axis;
- the dosing drum being positioned between a continuous strip of filter material, movable along a feed direction, and a primary hopper for containing a primary infusion product;
- the dosing drum including a plurality of radial chambers each configured for receiving a quantity of primary product forming a first dose at the primary hopper and, respectively, releasing the first dose above the continuous strip of filter material, in such a way as to form a succession of first doses, equidistant from each other, along the continuous strip of filter material, the radial chambers being movable in rotation the primary hopper, where the radial chambers receive the first doses and above the continuous strip of filter material where the radial chambers release the first doses;
- an independent dosing unit for feeding a secondary aromatizing or sugar product defining a second dose, the independent dosing unit being positioned downstream of the dosing drum relative to the feed direction of the continuous strip of filter material;
- the independent dosing unit including controlled release elements configured for placing the second dose at least partly on a corresponding first dose deposited on the continuous strip of filter material passing under the independent dosing unit to define a mixed dose of primary product and secondary product;
- the independent dosing unit comprising a feed channel for feeding the secondary product and an extractor screw positioned in the feed channel and constituting the controlled release elements.
A method for feeding infusion products comprising the following steps:
- preparing a continuous strip of filter material, movable along a feed direction;
- depositing a first controlled quantity of a primary infusion product, defining a first dose, on the continuous strip of filter material in such a way as to define a succession of first doses, equidistant from each other, via a dosing drum rotating about an axis;
- downstream of the depositing of the first controlled quantity of the primary infusion product, relative to the feed direction of the continuous strip of filter material, depositing a second controlled quantity, different from the first quantity and defining a second dose, of a secondary aromatizing or sugar product, on a corresponding first dose deposited on the continuous strip of filter material in transit, via an extractor screw feeder, to define a mixed dose of primary product and secondary aromatizing or sugar product.
